Break element out of container

Question

I have all my content wrapped in a container element with a fixed width.

But I have a <div> that I want to "break out" of that container to span the full width of the page.

As you can see in that example, I've got the <div> to break out, but since it's positioned absolutely, it doesn't affect the flow of the page...which is what I'd like it to do.

I want it to act like it's in the flow of the page, but expand the full width of the window.

Answer 1

Another idea, which in modern browsers does stretch the .breakout only to the width of the browser window:

body, html {    overflow-x: hidden;    margin: 0;    padding: 0;  }    div {    padding:0.5em;  }    .container {    width:300px;    background-color:rgba(255,255,0,0.5);    margin:auto;  }    .breakout {    margin:1em -100%; /* old browsers fallback */    margin:1em calc(50% - 50vw);    background-color:rgba(255,0,255,0.5)  }

<div class="container">  Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

Edit: The one and only Chris Coyier explains Full Width Containers in Limited Width Parents, which is somewhat similiar.
